Mastering Ansible, 4th Edition - Fourth Edition

By: James Freeman, Jesse Keating

Overview of this book

Ansible is a modern, YAML-based automation tool (built on top of Python, one of the world’s most popular programming languages) with a massive and ever-growing user base. Its popularity and Python underpinnings make it essential learning for all in the DevOps space. This fourth edition of Mastering Ansible provides complete coverage of Ansible automation, from the design and architecture of the tool and basic automation with playbooks to writing and debugging your own Python-based extensions. You'll learn how to build automation workflows with Ansible’s extensive built-in library of collections, modules, and plugins. You'll then look at extending the modules and plugins with Python-based code and even build your own collections — ultimately learning how to give back to the Ansible community. By the end of this Ansible book, you'll be confident in all aspects of Ansible automation, from the fundamentals of playbook design to getting under the hood and extending and adapting Ansible to solve new automation challenges.

  1. When creating or deleting VM instances on OpenStack, which inventory host should you reference in your play?

    a) The OpenStack host

    b) localhost

    c) The VM Floating IP address

    d) None of the above

  2. How would you reference a newly created virtual machine in a second play without having to use a dynamic inventory script?

    a) Use ansible.builtin.raw commands.

    b) Use commands.

    c) Use ansible.builtin.add_host to add the new VM to the in-memory inventory.

    d) You need to use the dynamic inventory plugin.

  3. You can still run dynamic inventory scripts directly in Ansible 4.x and newer, just as you could in Ansible 2.x releases.

    a) True

    b) False

  4. To use a dynamic inventory script, and set its parameters, you would now (assuming the collection is already installed):

    a) Define a YAML inventory file with the plugin name and parameters.

    b) Reference the dynamic inventory script in the -i parameter of ansible/ansible-playbook.

    c) Put the plugin name in your play definition...
